Hi All, I actually have an Insignia Flex 10.1 NS-P10A7100 which isn't listed here. My problem is a broken/malfunctioning headphone jack in the tablet. I hardly get any sound, I have to wiggle my headphone jack around inside tablet and hold it at a certain point to get the best sound I used to get, also sometimes it sounds like its underwater thru the headphones. The speakers work perfectly fine, no issue there. Do I need to replace the headphone jack inside of the tablet? Where do I find a replacement part and instructions on how to replace? Thanks in advance for your suggestions.
